Two supramolecular systems were constructed based on fluorene-based π-conjugated monomers with or without spiro structures, respectively, and their self-assemble behaviour and optical properties were investigated. Concentration-dependent 1H NMR and viscosity measurements indicated a transition from cyclic or oligomeric species at low concentrations to linear supramolecular polymers at high concentrations in the system without spiro structures. In contrast, the formation of cyclic species is
